List of essential documents to be certified for Irish Naturalisation

As a devoted Peace Commissioner who is extensively involved in certifying documentation for naturalisation applications, several applicants are bewildered as to where they may obtain the statutory declaration or the passport certification form.


This blog post serves an important purpose: it deconstructs the often-confusing landscape of document requirements for persons seeking naturalisation in Ireland. My goal is to provide a clear guide that alleviates the anxiety surrounding document certification.

Navigating many pieces of paperwork, such as birth certificates, passports, marriage certificates, evidence of residence, and character references, can be difficult. Through this blog, I hope to shed light on the essential documents required for certification only. Each heading will be linked to the appropriate INIS-provided Word document, certification form, and statutory declaration for individual applications, expediting the process and providing applicants with a clearer route towards their naturalisation journey.


  • A certified colour copy of the biometric page of your current in-date passport. The colour copy must be certified and the passport certification form by a solicitor, commissioner for oaths, peace commissioner or notary public.

  • A certified copy of your original civil birth certificate, and a copy of a translation into English if the certificate is in a language other than English or Irish.


  • Above two and Certified copies of all documentation proving your Irish associations e.g. all birth and/or marriage certificates or civil partnership agreements needed to show association, a certified copy of foreign birth registry entry, copy of naturalisation certificate or certified copy of passport page with photograph, etc.

You should satisfy yourself that your registered relationship is recognised before making an application based on being the civil partner of an Irish citizen.
